HAN Port

In practice

In practice, the HAN port means that a third-party app - energy monitoring, smart home control, charge optimisation - can retrieve real-time electricity data directly from the meter without going via the network operator or ElhubNational hub for metering data and market processes in the Norwegian electricity market.. Data is typically updated every 2 seconds and includes instantaneous power (kW), voltage per phase and accumulated energy (kWh). To activate the HAN port, the customer must give explicit consentThe end user's expressed permission for someone else to see or process information about them. In the power market it is the consent that gives a third party access to metering data. to the network operator - typically via a self-service portal. From an IT perspective, HAN port data is valuable for aggregators and flexibilityAbility to change power consumption or production in response to price signals or system operator needs. services: real-time metering enables second-by-second control of charging stations and hot water heaters. The data format is M-Bus or RJ45 and requires a local reading unit (HAN reader) or compatible IoT gateway to be interpreted.
